Abstract: ABSTRACT  In a vacuum system for subjecting a workpiece such as a semiconductor substrate to a beam of energy, for example as in cathodic sputtering, temperature rise of the workpiece is inhibited by mounting the workpiece in minimal thermal contact with the support structure, and orienting it so that the back surface of the workpiece, that is, the face opposite to that upon which the energy beam impinges, is directed to a black body or low temperature portion of the vacuum chamber.  In combination with this technique, the back surface is suitable treated to increase its emissivity such as, for example, by applying thereto a black coating.

Abstract: ANALOG-TO-DIGITAL CONVERSION APPARATUS     ABSTRACT OF THE DISCLOSURE           An analog-to-digital conversion apparatus wherein, in one embodiment, an input analog current is applied to an input of an integrating circuit, while a switching circuit allows a precision reference current to be summed with the input analog current at the input of the integrating circuit during a first mode of operation of the switching circuit and prevents the precision reference current from being applied to the input of the integrating circuit during a second mode of operation of the switching circuit.  The integrating circuit generates a first signal proportional to the integral of the sum of any currents applied to its input.  In response to the first signal and to clock pulses, generator means develops an incremental pulse width modulated signal to precisely control the first and second modes of operation of the switching circuit.  The incremental pulse width modulated signal and clock pulses are then utilized by an output circuit to generate a digital representation of the amplitude of the input analog current.

Abstract: METHOD FOR PREPARING AMINO COMPOUNDS     Abstract of the Disclosure Organic diamines can be prepared by first reacting a tertiary mono-amine with glyoxal and reducing the formed diimine in the presence of hydrogen and a hydrogenation catalyst.  Additional advantages are derived by carrying out the reduction step in the presence of a lower alkanol and in the presence of the tertiary mono-amine used to make the diimino compound.  The diamino compounds thus obtained are useful as catalysts in the preparation of polyphenylene oxide resins.
